Wheel spindle air blowing design

Wheel spindle air blowing design could create positive pressure. It effectively prevents dust going into the spindle, and maintains the internal coolant of the spindle. The catrige spindle itself has a outer spiral groove design, and it could effectively prevents the spindle from thernal raising.

Rigid rib-box structure

Rigid rib-box structure is consist with the same material level of Meehamite base casting, ensuring the machine rigidity and stability. Machine net weight: 2,200kg.

15HP spindle motor

Heavy duty spindle with 15HP spindle motor allows the machine to grind hard material or to grind with creep feeding operation

Machine design

435mm（17.12“）wide column design: Comparing with other manufacturer, it provides better stability and rigidity.

Machine design

774mm wide machine base design provides excellent machine rigidity, and low dynamic grinding operation

X Axis Working table guideway double V design

X Asis guideway is precisely hand scraped, oil firm lubrication supplied, and Turcite-B coated to ensure positioning accuracy and long term usage.

Column Type Integral "T" Shape Base

The integral "T" shape base is manufactured from Meehanite casting, with tempering & stress-relief treatment to ensure structure stability. The base is 2.5 times longer than the worktable. This design allows the work table to not only be fully be fully supporting during the whole travel, but also increases the rigidity when grinding.
The worktable slideways are modified as double V guideways. Deepened and widened guideway with large span design enables the worktable to move steadily and smoothly for large workpieces grinding. Special lubrication circuit design ensures the worktable to be fully supported by oil film pressure and decrease the frictions to prolong the use time of the machines.
The guideway lubrication system comes with a pressure switch sensor to make sure the machine has enough oil film pressure.

Specifically Built for Mold and High-tech Electronic Industries
E-tech Easy Series Surface Grinders present unique grinding accuracy and surface finish. The column type structure design. Easy series are all embedded a PLC control panel and a touch screen for easy operation; furthermore, the auto-grinding function meets the target of time saving and high efficiency.

Saddle Type Structure

The base uses strong box structure. The highly rigid base provides steady support that ensures the long-term precision.
The double V design of the base slideways improves the supporting stability.
The interior strengthened rid design effectively increases the structure rigidity.
